Plastic plants and ornaments can become coated in algae and organic deposits which spoil their appearance. Plastic Plant Cleaner helps keep your plastic plants and ornaments looking spotless! Simply remove your dirty plastic plant/ornament from the aquarium, place it in a bucket of water, add a cleaning tablet and leave it to fizz and dissolve overnight (or minimum of 8 hours). In the morning pour away the cleaning solution and rinse the plant/ornament before adding the neutraliser solution, your plastic plant/ornament is then ready to be placed back in your aquarium!
